The all new Model 1830-R Optical Power Meter is a completely redesigned optical meter, replicating much of the functionalities and specifications of the legacy 1830-C Model. The 1830-R is a perfect drop-in replacement for your existing 1830-C, which was also the most popular Newport meter used in fiber optic component production and testing.
DC power measurements can be displayed in units of W, dBm, dB, and Relative Measurement on the instrument’s bright 4 1/2 digit annunciated LED, providing wide dynamic range with power sensitivities down to 10 pW and full scale readings up to 2 W (detector dependent). Relative power measurements, in reference to a previously stored value, is performed with the result displayed either as a ratio or dB.
USB2.0 is the standard computer interface, while the 1830-R-GPIB model offers additional IEEE-488 (GPIB) and the RS-232C ports. Both the 1830-C and the current 19xx-C commands are supported. A built-in beeper, which changes its frequency as a function of incident optical power, can be utilized to optimize optical beam alignment. The analog output that provides a voltage proportional to the detector current can be used for fast control loop applications.

Compatible with 818 and 918D Series Photodiode Detectors
pW to Watts of optical power, depending on the detector models, can be accomplished with any one of Newport’s 818 (see Low-Power Calibrated Photodiode Sensors) and higher-end 918D Series (see Low-Power Calibrated Photodiode Sensors) UV, Silicon (Si), Germanium (Ge) or Indium Gallium Arsenide (InGaAs) Detectors, covering 200–1800 nm wavelengths. The 918D Series Detectors have a built-in temperature sensor utilized for sensing and actively compensating for temperature-induced measurement fluctuations, making them the most advanced photodiode based detectors. Also available from Newport are fiber optic detectors (see Integrating Sphere Fiber Optic Sensors). Please see Low Power Sensor Selection Guide for a power meter/detector compatibility chart.
